Plantronics Savi 740 Wireless Office Headset System
The Plantronics Savi 740 is our convertible wireless headset system built for professionals who manage calls across desk phones, computers, and mobile devices throughout the day. You get three-way wireless connectivity through a single base station, switching seamlessly between your office phone line, PC softphone applications, and Bluetooth-enabled mobile without changing headsets or juggling multiple devices.
We designed the Savi 740 around DECT 6.0 wireless technology, delivering enterprise-grade security and up to 350 feet of roaming range from the charging base. The convertible wearing style gives you the flexibility to choose over-the-head, over-the-ear, or behind-the-neck configurations using the same lightweight headset frame. Whether you’re on back-to-back conference calls, training webinars, or switching between your CRM platform and client check-ins, the Savi 740 keeps you connected with up to 7 hours of talk time per charge.
Wireless performance & connectivity
Tri-connectivity base station architecture
Our Savi 740 base station manages all three connection types simultaneously through a unified charging dock that sits on your desk. The base connects to your desk phone via the included phone cable, links to your computer through USB for softphone applications like Microsoft Teams or Zoom, and pairs with your smartphone over Bluetooth 2.1+EDR.
You switch between active lines with a single button press on the headset. An LED indicator on the base shows which line is live, and the system automatically prioritizes incoming calls based on your pre-set preferences. This architecture eliminates the cable clutter and device-swapping that slows down multi-line workflows, particularly for IT help desk staff, executive assistants, and sales teams who field inquiries across multiple channels.
DECT 6.0 security and interference avoidance
We chose DECT 6.0 as the wireless protocol for the plantronics savi 740 because it operates in the dedicated 1.9 GHz band, separate from the crowded 2.4 GHz spectrum where Wi-Fi routers, Bluetooth peripherals, and microwave ovens compete for bandwidth. This separation virtually eliminates the audio dropouts and static common with older 2.4 GHz wireless headsets in dense office environments.
DECT also delivers 64-bit digital encryption between the headset and base, meeting enterprise security standards for voice communications. The adaptive frequency selection scans for the cleanest channel within the 1.9 GHz band and switches automatically if interference is detected. You get consistent call clarity even when moving between floors or into conference rooms with heavy wireless traffic.
Convertible headset frame and wearing options
Interchangeable wearing styles
The Savi 740 ships with three wearing accessories that attach to the same lightweight headset frame. The over-the-head band distributes weight evenly for all-day comfort during long training sessions. The over-the-ear hook offers a more discreet profile for customer-facing roles. The behind-the-neck option keeps hair and glasses unobstructed while maintaining secure placement during active movements.
You swap between styles in seconds without tools. The monaural speaker sits against one ear, leaving the other ear free to hear office conversations and environmental cues. The noise-canceling microphone boom adjusts along a 270-degree arc and features a red mute indicator visible to colleagues during video calls. The microphone’s wideband audio codec captures frequencies from 150 Hz to 6.8 kHz, reproducing your voice with clarity that standard narrowband phone systems can’t match.

Common questions about the Savi 740
Yes. The Savi 740 connects to your computer via USB and registers as a standard audio device, compatible with Microsoft Teams, Zoom, Skype for Business, Cisco Jabber, and other softphone applications. The call answer/end button on the headset controls in-app calls directly, and the base station’s USB connection delivers wideband audio for clear voice transmission during video conferences.
The Savi 740 provides up to 350 feet of roaming range from the base station in open office environments. Actual range depends on building materials—concrete walls, metal studs, and elevator shafts will reduce coverage. In typical corporate offices with drywall partitions, most users experience reliable connectivity throughout a 10,000-square-foot floor without dropouts.
The Savi 740 is compatible with most desk phones that have a standard RJ-9 or RJ-11 handset jack, including models from Cisco, Avaya, Polycom, Mitel, and Nortel. Some proprietary phone systems require a separate electronic hook-switch (EHS) cable or handset lifter accessory for remote call answer/end functionality. Check your phone manufacturer’s compatibility list or contact our support team with your specific phone model.
Press the call button on the headset to answer an incoming call on any connected line. To manually switch between active lines, press and hold the call button for two seconds until you hear a tone, then press again to cycle through available connections. The base station’s LED indicators show which line is currently active—blue for desk phone, purple for PC, and red for mobile.
The Savi 740 base supports conference mode, allowing up to three additional Savi headsets to subscribe to the same base for team collaboration on a single call. Each participant hears the conversation and can speak, creating an ad-hoc conference bridge. This feature requires all headsets to be Savi series models and works best for small team huddles rather than large conference calls.
If the battery depletes completely during a call, the connection will drop. The headset provides a low-battery warning tone approximately 15 minutes before shutdown, giving you time to either swap in the spare battery or move to a wired headset. We recommend keeping the spare battery charged in the base station’s secondary charging slot for quick hot-swaps during marathon call days.
We back the Savi 740 with a one-year limited warranty covering defects in materials and workmanship under normal use. The warranty includes the headset, base station, batteries, and all included accessories. Routine wear items like ear cushions and microphone windscreens are considered consumables and are not covered. Extended warranty options and advance replacement services are available through our support team.
